Question

CHAPTER 15 Neck and Trunk 179 8. Perform trunk flexion (trunk curl) in supine C. What class lever is this motion? Identify and position. Compare the range of trunk motion achieved with the range of motion achieved in Questions 6 and 7 A. Where does the additional ROM come from arrange the axis, resistance, and force in the proper order. in the sit-up exercises in Questions 6 and 7? D. Which muscle(s) control the motion? B. Which method, sit-up or trunk curl, is less likely to increase lumbar lordosis? E. What type of contraction has the agonist Trunk curl performed? Explain your answer. 11. Apply paper tape strips to your partner's abdomen to represent the layers of the abdominal muscles. Apply the strips from the origin to the insertion of each muscle. Write the name of the muscle on each tape. Ensure that the tape strip "muscles" are applied in the correct layer. 9. With your partner lying on a table with hands on shoulders and legs extended, place one of your hands under your partner's lower lumbar region. Place your other hand on your partner's abdomen. Ask your partner to press the low back into the table (lumbar flexion). Complete the following: A. A. Deepest layer isveabdonin B. Middle layer is nk Crsl obliqu C. Outer layer is Etrnsl dbl.aue Motion Performed Lumbar flexion 12. In each of the activities that follow, identify which muscles are the agonists. Starting position is the sition: B. If your partner is unable to press the low A. With the head in midline, ask your partner to back into the table, which muscles may be too short to permit the movement to occur? flex the head and neck only tuck the chin. partner to lift the head off the table. B. With the head in midline, ask your partner to C. If your partner is unable to press the low back C. With the head turned to the left, ask your into the table, which muscles may be too weak or long to perform the movement? 13. With your partner sitting and facing you, palpate the carotid artery in the space between the thyroid 10. In the standing position, slide your left hand down the side of your leg, thereby bringing your shoulder closer to your knee A. What motion did you perform? B. Is gravity or muscle the force? Underline the cartilage (Adam's Apple) and the SCM muscle. lsid you pe Because this artery supplies much of the blood to you perform? Lett latthe brain, be cautious: Do not palpate both sides unktexi at the same time! correct answer

Explanation / Answer

8; LUMBAR LORDOSIS IN SIT UPS AND TRUNK CURL.

In case of the sit ups the hip and knees are always flexed whereas in case of thetrunk curl the hip and knee are extended .

so the LUMBAR lordosis is pronounced in case of the trunk curl.whereas in sit ups the flexion leads to the elimination of the lordotic curve.

9: LUMBER FLEXION :

Agonist - Rectus abdominis, internal oblique , external oblique , latissimus Dorsi and psoas .

Antagonist - erectile spinae group of muscles and gluteus maximus.

devoid of lumber flexion due to;

Short muscle of LUMBER EXTENSORS.

Long muscle fiber of LUMBER FLEXORS .

Weakness of LUMBER FLEXORS.

10; THE movement is LATERAL TRUNK FLEXION.

It is done actively so the muscular force is predominant but the gravitational force is assistive in nature.

-THE 3RD ORDE LEVER works as the shoulder joint forms the fulcrum , the distal forarm the load and the arm has effort .

-Muscles involved are : Quadratus lumborum , external oblique , internal oblique

these are the agonistic group ofmuscles.

- there is CINCENTRIC contraction by the agnostic muscles.

11: deep layer- transverses abdominis muscle

MIddle later - internal oblique muscle

superficial layer- external obliquemuscle

12; - HEAD AND NECK FLEXION: sternocleidomastoid , scalene anterior , scalene posterior and scalene medius.

-CHIN TUCKING MUSCLE: lingus capitis and longus colli

-HEAD rotated left and elevated; Right side sternocleidomastoid.
